Abstract Bridge is an adjunct structure as a connection between two edge of road that has been separated under several geographical features. The object research the continuous box girder bridge. Light Rail Transit loading implemented on bridge with 1 and 2 trainsets LRT study case. structure’s geometry, support, material, are modelled finite element analysis software. natural frequencies in ex...

Experimental investigation of the ultimate resistance of slender, steel-plate girder web panels to combined shear-and-patch loading indicates significant interaction between shear loading and patch loading. However, an existing interaction formula is based on experimental results. Herein, an improved design procedure for slender plate girders subjected to combined shear and patch loading is pro...

in this paper, a sensitivity analysis of artificial neural networks (nns) is presented and employed for estimating the patch load resistance of plate girders subjected to patch loading. to evaluate the accuracy of the proposed nn model, the results are compared with the previously proposed empirical models, so that we can estimate the resistance of plate girders subjected to patch loading. the ...

R f search has produced two major procedures for assessing creep and shrinkage; the ACI 209 method' and the CE$-FJP method.' Laboratory research into concrete creep and shrinkage has been conducted for decades, and excellent analytical procedures for evaluating structures for creep and shrinkage have been presented in the literature.'-5 Creep and shrinkage are factors in the design of a variety...

There is growing use of FRP composite materials in the civil infrastructure for rehabilitation of deficient bridge components including deck slabs and girders. However assessment of the effectiveness of rehabilitation over time and monitoring the progression of damage or change in load paths between the structural components, caused by sequential strengthening of the components, has not been un...

There are multiple configurations permitted for a cable stayed bridge such as the number of spans, tower shapes, and cable arrangements. Therefore it is always important to study the behaviour of these types of structures against strong winds so that aeroelastic instabilities do not appear. This paper contains detailed aeroelastic analyses of three cable stayed bridges of very different configu...

Abstract The jointless bridges includes integral bridges, semi-integral and extended deck bridges. adopts an abutment, its main girder, abutment pile under are fixed together to bear the force together. expansion joint device cancelled, integrity, durability driving comfort of bridge improved. In this paper, a simply supported girder in Fujian Province China is taken as research background, it ...
